I prefer the comments of Elon Musk:
"I'm the chief engineer, so I'd just like to say if it goes right, it's credit to the SpaceX-NASA team. If it goes wrong, it's my fault."

An SLS vendor blocked me for asking why a cover was being milled from a multi-ton bit of aluminum when it could be [sheet metal/composite] part.
I'm glad we're going back to the moon, but I'm worried it will be unsustainable until we deal with the skeletons of Apollo contractors.
"Senior agency officials have told us that at current cost levels the SLS program is unsustainable and exceeds what NASA officials believe will be available for its Artemis missions."

Elon's sentiments today are exactly right : "I'm the chief engineer of this thing so I'd just like to say that if it goes right, it's credit to the SpaceX-NASA team, if it goes wrong, it's my fault." I wish this attitude was more common (and applied to situations like a pandemic)

I suggest devoting our entire Mars-DSN bandwidth budget to downlinking launch video from the rover. The public relations revolution would probably be bigger than getting the samples back.
After the samples are recovered, we’ll launch the first rocket from the surface of Mars to bring these samples back to Earth.

Blue Origin has filed a protest with the Government Accountability Office over NASA’s selection of SpaceX in the Human Landing System competition. “NASA has executed a flawed acquisition for the Human Landing System program and moved the goalposts at the last minute,” it said.

This is catastrophically bad for the environment. Nuclear power is a key part of our sustainable energy future. Nuclear fission is demonstrably safer than alternative baseload power sources like coal.

The moon wasn't designed to be landed on. 33 engines weren't meant to go on one rocket. People didn't evolve to live and work in space. We can imagine and build futures that are better than what we are dealt. It belongs in a museum.
Gatens: ISS wasn't designed to be taken apart. Think about cables (i.e. electrical) that run through it and would have to be disconnected. Would be like trying to take the bathroom out of your house.

I'm thrilled they went with solids. I'd been hearing rumors of a hybrid and it made my skin crawl. Let's go get some Mars rocks!
After years of studies in preparation for launch of a robotic Mars Sample Return mission in 2026, NASA has settled on a solid-fueled design for a miniature rocket with a first-of-its-kind purpose: Launching a payload from Mars for a trip back to Earth.
